The Castelli Aero Race Jersey saves 10 watts at 40km/H compared to a typical race-cut jersey - that’s 40 seconds saved every hour! Velocity fabric with Prosecco treatment on the front and shoulders is lightweight, stretchy, super evaporative, and reduces wind drag. The mesh back enhances breathability, and Giro++ elastic arm openings lie flat for smooth airflow. This aerodynamic cycling jersey will save you seconds, so you can sit around and eat cookies all winter. Just kidding - that’s a bad idea.
